They should've stuck Moto with SD socs and Lenovo with MTK ones but looks like it is reversed now. With Huawei, Moto and Asus increasing their prices Xiaomi and Lenovo will have great battle in entry to lower midrange phones!

Snapdragon 430 is made on the 28nm technology, so power consumption will suffer despite the bigger battery. An ideal midrange phone for battery life would have Snapdragon 625 and a 4000 mAh battery. It would probably last 3-4 days.
